The optical sensors were   integrated in the  same fabrication CMOS process with the analog to digital   converters,  which are based on sigma-delta modulators. Signals proportional   to the  intensity of the transmitted light through the biological   fluids, which are  proportional to the biochemical substance concentration, are\t available at  the output in the form of bit streams allowing simple computer\tinterfacing.  Although the sigma-delta converters designed for this project   have a very  simple architecture, they have other advantages relatively to   other  interfacing devices used with the same purpose, namely, the\tnoise that is  integrated with the signal and then digitally filtered, which   means that,  except for its small quantity in the signal band, it is   eliminated by the  device.<\/jats:p>","DOI":"10.1149\/1.2813489","type":"journal-article","created":{"date-parts":[[2007,11,28]],"date-time":"2007-11-28T23:12:22Z","timestamp":1196291542000},"page":"171-178","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sigma-Delta Analog to Digital Converter for use in Lab-on-a-Chip Devices for Biochemical Clinical Analyses"],"prefix":"10.1149","volume":"4","author":[{"given":"G.","family":"Minas","sequence":"first","affiliation":[]},{"given":"J.
